There is no batch conversion offered in Premiere Elements (any version) so that you put 500 mp4 files on its Timeline and you export 500 indivdual mp4 files.
You do not seem wanting to put 500 individual mp4 files on your Timeline and get one file mp4 representing all 500 mp4 files.
A program such a MPEG Streamclip might be something that you would want to look into for that feature.
Please check out the above and let us know if any of that worked for you.
Thanks for the tip. I will take a look at it. I bought Premier with batch conversion in mind. I thought the organizer could do it but I guess not. Thanks for the quick reply.
If you intend to produce the individual video as .mp4 exported from Premiere Elements, please do not hesitate to ask for some suggestions for export choices including customization of the export settings.
Glad for the opportunity to be of assistance.
